BATTERY MANAGEMENT METHOD AND BATTERY SYSTEM PROVIDING THE SAME

The invention relates to a battery management method and a battery system providing the same. A battery system according to the present invention comprises: a battery; and a BMS that controls charging of the battery in accordance with a normal mode that uses a first battery capacity between a first lower limit SOC (state of charge) and a first upper limit SOC, the first lower limit SOC being smaller than the second lower limit SOC, and an eco-mode that uses a second battery capacity between a second upper limit SOC and the second lower limit SOC, the first lower limit SOC being smaller than the second lower limit SOC, and the second upper limit SOC being smaller than the second lower limit SOC. And the first upper limit SOC is greater than the second upper limit SOC. 本发明涉及电池管理方法和提供该电池管理方法的电池系统。根据本发明的电池系统包括：电池；以及BMS，该BMS根据使用第一下限SOC(充电状态)和第一上限SOC之间的第一电池容量的正常模式或使用第二下限SOC和第二上限SOC之间的第二电池容量的环保模式来控制所述电池的充电，其中，所述第一下限SOC小于所述第二下限SOC，并且所述第一上限SOC大于所述第二上限SOC。
